Stats: Swisshelm is 5' 9" tall, 150 pounds. At age 45, she is the oldest person of Team USA's 230 Olympic team members in 2014. (The youngest is freestyle skier Maggie Voisin, age 15.) Swisshelm has two teammates who are 40-years old, while the others are 39 and 29.

Olympic record: This will be Swisshelm's second appearance at the Winter Olympics. Her team finished fourth at the 2002 Salt Lake City games. Swisshelm says that this will be her last appearance at the Olympics.

"It's time for the next generation," she told the Chicago Tribune in November.

Background: Swisshelm has been curling since she was 10 years old in 1980. She explains how she approaches the sport today.

"It's about paying attention to your body, training smarter because harder is not an option, and knowing that your mental game can best a younger opponent's physical one," Swisshelm said, according to the U.S. Olympic Committee website. "Also, my go-to recovery drink makes a difference – there's nothing like chocolate milk to help you feel like a kid."
